6. An Investigation of Mixed Cellulose Esters and Acyclic Polyacetates: Effects of Side-Chain Lengths and Degrees of Ring-Opening
Sammanfattning : Bio-based polymers produced from natural sources are gaining an increased interest as potential replacement for today’s conventional fossil-based plastic polymers. Their use is already wide in many large-scale industrial areas such as healthcare, personal care, and food. LÄS MER
7. Dissolution of cellulose in aqueous hydroxide base solvents
Sammanfattning : As we move towards a circular bioeconomy, new and advanced materials based on cellulose are constantly developed. Unlike most plastics or metals, cellulose cannot be melted, and therefore dissolution is an important tool for processing of cellulose but also for analytical purposes. LÄS MER
8. Effects of methyl jasmonate on chemical defenses of conifer seedlings in relation to feeding by Hylobius abietis
Sammanfattning : The chemical elicitor methyl jasmonate (MeJA) could replace insecticides in Europe and Asia for protection of young conifers against the pine weevil (Hylobius abietis). This thesis mainly focuses on the effects of MeJA treatment on chemical defenses of conifers from seedling batches with documented field resistance. LÄS MER
9. Development of advanced chemical biology tools for microbiome metabolism : Chemoselective probes for enhanced metabolomics analysis
Sammanfattning : The human microbiome has a profound impact on host physiology by generating highly reactive compounds that can contribute to the development of diseases. These microbial metabolites have a substantial potential that can serve as valuable indicators or biomarkers for different health conditions. LÄS MER
10. Investigations of Solvent Systems Based on bis-triazine-bipyridine (BTBP) - class Ligands for the Separation of Actinides from Lanthanides
Sammanfattning : Shortages of fossil fuel and other political movements contributed to the nuclear energy “renaissance”.Nuclear energy, however, is not free of challenges, one of them being nuclear waste management. LÄS MER
